Fury
Hugh saw Aric's body completely immersed in black fire. Strangely, he could not feel any heat nor warmth from the black fire, only the chilling cold.
The black fire spread because of the explosion. There were small black flames that caught onto the walls, destroying those parts that were touched.
The walls were not burnt but freezing. The walls that were supposed to melt into a liquid-only became more solid until it was so brittle that it shattered into a million pieces.
Hugh looked at Aric with a shocked and confused expression. Aric had not only come back alive with not a scratch on his body, but his burning fire had also turned into something else.
He looked down and saw that a part of his clothes had black flames spreading, so he quickly patted them down. This was his reflex acting, and he did not think about the consequences.
